Yes, it will work, but with caveats.
Correction: The source claimed 127V for Nova Scotia—**this is incorrect**. Canada uses the same 120V/60Hz standard as the US. Your US curling iron will operate **normally** on voltage.
Both countries use **Type A (2-flat) and Type B (2-flat + ground)** plugs. **No adapter needed.** Your US plug fits Canadian outlets perfectly.
Since voltage is identical, heating speed and temperature will be **exactly the same** as in the US. No converter or transformer required.
Pack your US curling iron for Nova Scotia—**plug in and go.** No adapter, no converter, no performance loss.
